Kristen Stewart parties with Ellie Goulding as Robert Pattinson films in Australia

13 FEBRUARY 2013

Kristen Stewart was spotted partying backstage at friend Ellie Goulding’s LA concert at the weekend while boyfriend Robert Pattinson was shooting his new film in Australia. The famously low-key Twilight actress found herself at the centre of attention when she was pictured with a group of friends after watching the British songstress perform.

She was almost incognito as she kept her head down low behind a fellow reveller but her trademark baseball cap worn backwards and sultry eyes gave the game away.

Kristen reportedly sparked up a friendship with Ellie after she featured on the Twilight: Breaking Dawn Part 2 soundtrack. The Starry Eyed singer is currently touring the US, putting on a series of free gigs, including a daytime one at LACMA (Los Angeles County Museum of Art), in order to raise her profile stateside. Kristen is a committed fan of Hereford-born Ellie and was spotted at one of her gigs in LA in November.

While the pair got into the party spirit, thousands of miles away Kristen’s Twilight co-star and beau was filming his new movie, The Rover. The couple have been hit with fresh claims that their relationship is in trouble after Kristen didn't walk the red carpet with Rob at the Golden Globes.

However, she did join him at the West Hollywood's Soho House private afterparty, until well after midnight. But they did not put in a loved-up appearance at the bash, with one onlooker commenting that the pair, "hung around each other, but [they weren't] on top of each other."

The Twilight couple's romance was thrust into the spotlight last summer when Kristen admitted a "momentary indiscretion" with film director Rupert Saunders, who is married to British model Liberty Ross.

There have been reports in the UK that Britain-born Robert called time on their relationship over Christmas, which they apparently spent apart. They did spend the thanksgiving break together, though, in the UK. They were last seen together in public in November, catching a flight out of New York's JFK airport.
